Question

我试图扩展基于烧瓶的项目https://github.com/hack4impact/flask-base/tree/master/app。这使用了app / init.py和蓝图中的应用程序工厂模式。

在app / init.py中我有：

import os
from flask import Flask
from flask_mail import Mail
from flask_sqlalchemy import SQLAlchemy
from flask_login import LoginManager
from flask_assets import Environment
from flask_wtf import CsrfProtect
from flask_compress import Compress
from flask_rq import RQ
from flask_admin import Admin, BaseView, expose
from flask_admin.contrib.sqla import ModelView
# from app.models import User


from config import config
from .assets import app_css, app_js, vendor_css, vendor_js




basedir = os.path.abspath(os.path.dirname(__file__))

mail = Mail()
db = SQLAlchemy()
csrf = CsrfProtect()
compress = Compress()


# Set up Flask-Login
login_manager = LoginManager()
login_manager.session_protection = 'strong'
login_manager.login_view = 'account.login'

from app.models import User


def create_app(config_name):
    app = Flask(__name__)
    app.config.from_object(config[config_name])
    app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
    # not using sqlalchemy event system, hence disabling it


    with app.app_context():
        m =app.url_map

    config[config_name].init_app(app)

    # Set up extensions
    mail.init_app(app)
    db.init_app(app)
    login_manager.init_app(app)
    csrf.init_app(app)
    compress.init_app(app)
    RQ(app)
    # adm = Admin(app, name='MyAPP')
    adm = Admin(endpoint='adminz', name='adz', url='/adminz')



   ......

    # Create app blueprints
    from .main import main as main_blueprint
    app.register_blueprint(main_blueprint)

    from .account import account as account_blueprint
    app.register_blueprint(account_blueprint, url_prefix='/account')

    from .admin import admin as admin_blueprint
    # from .admin import admin_blueprint
    app.register_blueprint(admin_blueprint, url_prefix='/admin')

    return app

模板/管理/ db.html：

<p>Hello world</p>

对于管理员观看次数（https://github.com/hack4impact/flask-base/blob/master/app/admin/views.py），我已添加：

from flask_admin import Admin, BaseView, expose
from flask_admin.contrib.sqla import ModelView
from app import adm as adm, db

class MyView(ModelView):
    @expose('/')
    def db(self):
        return self.render('admin/db.html')


# admin management setup
@main.route('/db')
def db():
    adm.add_view(MyView(User, db.session))

当我打开时，我的管理信息中心不是刻录管理员基本视图：

 127.0.0.1:5000/db

我做错了什么？

编辑：

按照您的指示，我将create_app更改为以：

开头

def create_app(config_name):
    app = Flask(__name__)
    app.config.from_object(config[config_name])
    app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
    # not using sqlalchemy event system, hence disabling it
    # adm = Admin(name='admin2', endpoint='/db', url='/db', template_mode='bootstrap3',base_template='admin/db.html')


    config[config_name].init_app(app)

    # Set up extensions
    mail.init_app(app)
    db.init_app(app)
    login_manager.init_app(app)
    csrf.init_app(app)
    compress.init_app(app)
    RQ(app)
    adm = Admin(app, name='MyAPP')
    # adm = Admin(endpoint='adminz', name='adz', url='/adminz')
    adm.add_view(MyView(User, db.session, endpoint='db'))

这导致：

文件＆＃34; .... flask \ app.py＆＃34;，第946行，在register_blueprint中（blueprint，self.blueprints [blueprint.name]，blueprint.name）断言错误：和之间发生了蓝图的名称冲突。两者都使用相同的名称＆＃34; admin＆＃34;。动态创建的蓝图需要唯一的名称。

EDIT2：

到create_app的末尾我已添加：

# Create app blueprints
from .main import main as main_blueprint
app.register_blueprint(main_blueprint)

from .account import account as account_blueprint
app.register_blueprint(account_blueprint, url_prefix='/account')

from .admin import admin as admin_blueprint
# from .admin import admin_blueprint
app.register_blueprint(admin_blueprint, url_prefix='/admin')
# app.register_blueprint(admin_blueprint, url_prefix='/ab')

with app.app_context():
    m =app.url_map

return app

我不确定你想看到什么，但是m.rules给出了：

 <Rule '/account/manage/change-password' (HEAD, GET, OPTIONS, POST) -> account.change_password>,
 <Rule '/account/manage/change-email' (HEAD, GET, OPTIONS, POST) -> account.change_email_request>,

编辑3：

我不得不说这是一个不可思议的答案！你真的教过我很多东西。我已按照您的指示更换了上述规则的网址。我10天前的原始计划只是使用基本的flask-admin CRUD功能。我对db.html模板不感兴趣（这只是我尝试过的）。

无论如何都试图更改管理蓝图的名称（您的号码1）。我在尝试将app / admin / init.py更改为：

之前尝试过此操作

from flask import Blueprint
admin = Blueprint('admin_blueprint', __name__)
from . import views  # noqa

现在我打开

http://127.0.0.1:5000/adminz/

我收到404错误

最终编辑：

问题由https://chat.stackoverflow.com/users/5819113/diego-quintana解决，他解释说创建蓝图的flask-admin与基于烧瓶的管理蓝图之间存在冲突。通过更改蓝图的名称和基于flask的项目的静态文件夹。 Flask-admin可以在不被覆盖的情况下工作。请参阅https://github.com/kc1/flask-base

endpoint
